Hot Rod Silverado is on a distinguished road

Dan, plug wires are nowhere near o2 sensor wires, only thing different are the headders are closer to the plug wires than the stock manifolds were

Take a spray bottle and mist the plug wires with water. Do this at night and then turn off the lights. If you see any blue flashing you have a grounding problem.
